Review on Flowmaster Super 44 409s Muffler (2.5 Inch Inlet/Outlet) by Aaron Masek
inefficient - exhaust and emissions
slightly louder than stock muffler, plus my gas mileage dropped by three mpg. called Flowmaster tech support and got an apology. I wish there were different reviews when I bought it but thought they were a reputable company.
Pros
- Noticeable internal resonance
Cons
- boring package
